EXPECTANCY-BASED JOB COGNITIONS AND JOB AFFECT AS PREDICTORS OF ORGANIZATIONAL CITIZENSHIP BEHAVIORS

This study investigated the importance of expectancy-based job cogniti ons and job affect (the affective component of job satisfaction) in he lping to account for ''organizational citizenship behaviors'' (OCBs; O rgan, 1988). Data pertaining to the expectancy-based job cognitions (i .e., expectancies, instrumentalities, valences), job affect, and OCB p erformance of 65 state finance agency employees were examined. We anti cipated that the effect of expectancy-based job cognitions on OCB woul d be partially mediated by affect-based job satisfaction. This expecta tion was confirmed in that, after controlling for negative and positiv e affectivity, generalized instrumentality beliefs were found to affec t OCB-altruism directly, as well as indirectly through the influence o f affect-based job satisfaction.
